SOLUTION: In a dice game, one fair dice is used. The player wins P 1000 if he rolls either 1 or a 6. He losses P 500 if he turms up any other face. What is the expected winning for one roll

Algebra ->  Permutations -> SOLUTION: In a dice game, one fair dice is used. The player wins P 1000 if he rolls either 1 or a 6. He losses P 500 if he turms up any other face. What is the expected winning for one roll      Log On

The probability to get any of 6 faces up is   for each and evry face.


Therefore, the expected winning for one roll is


         =


      =  =  = 0.    ANSWER
